RE: How much?
I paid $460 for a shoulder mount professionally tanned hide this year. I have seen many mounts since I first sent him away 6 months ago and now that I know what to look for there are A TON of poorly done mounts out there.........and of some great bucks too [:'(]
You get what you pay for.........make sure you know the guy (get recommendations) and see some of his work. Once you are happy he will do a great job then don't worry about the price because it will be worth it in the end.
5-10 years down the road your heart will either soar or break every time you see the mount on the wall..........you decide.
